lavatories and the like, and the general obl ject ot' my invention is to provide asimple and ei'l'ective mechanism :tor the purpose.

The various features of noveltyvfhich characterize my invention are pointed out with particularity in the claims annexed to and Aforming a part oi this specification.

For a better understandingofthe invenf4 tion, however, and the specific objects obtained thereby, reference should be had to the accompanying drawings `and descriptive matter in which I have illustrated and described a preferred embodiment of my" in vcntion.

0f the drawings: y i Figure l is a sectional elevation of a por tion of a lavatory of conventional form to which my invention is applied; Y

Fig. 2 is an elevation taken at right angles to Fig. l, showing a portionV of the Waste valve mechanism;

Fig. 3 is an elevation Witliparts broken away and partly in section on the `line 3-3 of Fig. 1, and

Fig. 4 is an elevation ot a portion of theV valve mechanism shown in Fig.l 1. i

In the drawings, A represents a lavatory basin and slab structure ol?` coi'iventional type. The structure A. is formed with the usual overiow passage .AQ-land the 'usual Waste outlet passage A? in the bottom oi' the basin bowl. Ah/Iounted in the passage A2 Iis the upper end of' the` Waste conduit. As shown this comprises a tubular section B provided. with an out-turned flange portion B and a conical valve seat at its upper ond and externally" threaded at its lower end.`

Between its ends, the section B isprovided with lateral ports B3 communicating with the overiiow pass-.ige A. The section `is secured in place by anut C screwedion to the threaded lower end "oit the section'B and engaging ajwasher C interposed be` tween the nut and the under side of the basin bowl.

In threaded engagement with the lower end of the tubular Waste conduit section li is another section E et the waste pipe. This section is provided with an opening in one side to receive the rotatable valve operating` member F, and has stuiing box provisions for preventing leakage out ci4 the waste con duit along the member F. As shown, lthe member F is provided with a collar F which fits against a flange `E forming the annular bottom or inner end ot' a stal-ting box E formed integral with the section C, and in which Vthe cylindrical body portion F2 oi? the member F received. (i represents a compressible, packing in the box E2, and E3 represents an externally tlircaded ring which surrounds the portion F2 oit the member F and is in threaded engagement with the internally threaded stuiling box E2 to compress the packing (i. The inner end oi the member F is in `the form of a cam arm F3, which may be swung back and forth between the 1 'full and dotted line positions shown in Fig. 3. Movement of the arm F in the clockwise direction` beyond the dotted line position of Fig. 3 is prevented by the stop rib Etiiormed 0n the inner wall of the member E, and turning `movement oi' the arm FS in the opposite direction beyond the full line position of Fig. 3 is prevented Yby the stop rib E5 also formed on the inner Wall oil the member E.

The purpose oi the arm F3 is to engage the lower end of the waste valve H and move it from the dotted line position into the 'full `line position at Fig. 3. When in the full line position shown in Fig. 8, the valve H is Wide open, as shown in Fig. 1. The valve H, aS shown, comprises the conical valve portion H proper, adapted to seat against the conical valve seatB,` and a depending stem portion provided with lateral guide ribs `H2 and formed at its lower end with a :toot .portion H, `the under side of which is directly engaged by the arm F3V of the member'li to open the valve. A screw I passing through a threaded orifice Vformed 'for the pnrposeintheupper end ol the `Waste conduit section E extends over the toot portion Hi of the valve, normally prevents the removalo the valve H. The partial retractionoi theserewl permits the removal ot i "es At its outer end the valve-operating meinber F is provided with an arm FfL which 1s apertured to provide a bearing, receiving the end portion of "a member K. The low'ermember K is in the form oi a rod bent at right angies to the body portion of the member. The lower end portion of the member K 1s formed with openings to receive cotter pins L fixing the axial position of this portionoi the rod with respect to the arm F Advantageously, as shown, there maybe a plurality of these openings to permit of adjustment necessary in applying the waste valve to diiicrent lavatories. The upper end of the rod K is screwed into a threaded opening formed in the lower end of a yoke member M. The latter is `formed at its upper end with an opening in which is swiveled the reduced lower end of the valve-operating plunger member O which passes upward through the basin slab and is yprovided at its upper end with the usual knob O. Advantageously, as shown, the rods K and O, while lying in the same plane,are notl in alinement with one another, but in tersect at an angle7 threaded opening in the yoke member M receiving the upper end of the member K and the passage of the member M receiving the lower end of the rod O, being correspondingly out oi' alinement with one another. Inf consequence of this arrangement, there is no tendency for the member M to rotate under the strains of use, and thus throw the valve-operating mechanism out of adjustment, even though a set screw M employed to prevent such rotation should be lost or lose its eiiectiveness. The member M is provided 'with apassage at its upper end, receiving the reducd lower end of the rod O on `which the member M is thus swiveled. A cotterpin O2 is passed through the lower portion of the rod O to hold the member M on the latter.

Advantageously, as shown, the cylindrical body portion of the memberF is appreciably larger in diameter than the outer portion of the member so that the washer member E3 maybe moved into place 1n assembling the apparatus `over the outer end F4 of the member F. It is, of course, possible to put the packing Gr in place in the same manner.

An important feature of my invention is the arrangement of the parts, as shown `in Fig. 3, so that when the arm F3 is moved from the dotted line position `of `Fig.` 3 into the full line position of f3, the valveengaging portion of the'arm F3 moves over the axis of rotation of the member F before the armF? engages the stop Incensequencdwhenfthe arm :F3 is intheposition 'shown in full linesfin` Fig, pressure ap plied-5to'lthefnpper end `of thewaste valve, `either manually 'orby thefwa'ter `escaping from the 'basin bowl, neither ltends to close the waste valve or to put any strain on any portion of the valve-operating mechanism which could be injuriously ai'tected thereby. lVhen the knob O is raised to close the waste valve mechanismthe rod O iis held in its upward position by the frictional resistance to the movement of the rod O through the guide sleeve P, and by the frictional resist ance to the rotation or the member F in the stuiiingbox. Advantageously, the guide sleeve P extends downwardly to provide a stop adapted to be engaged by the `upper end of the yoke member M on an upward movement of the latter approximately the same as that required to move the arm Fs into engagement with the stop E4. While in the normal condition of the apparatus but one of the two stops just provided to limit the upward movement ot' the rod O `is necessary, the presence of the two stops prevents undesirable movement of eitherthe rod `O or the arm F, incase of an improper adjustY ment of the apparatus. i
